Severe Spinal Injury in Hirayama Disease
Cecilia Quarracino,Florencia Aguirre,Carlos A. Rugilo,Luciana De Negri,Andrés M. Villa 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.5
Hirayama disease is a rare neurological disorder characterized by an insidious progressive subacute unilateral or bilateral weakness of the hands and forearm muscles leading to a painless amyotrophy. The disease primarily affects young men in the second to third decades of life. It has always been described as a second motor neuron disease, thus sparing the pyramidal and sensitive pathways. It usually has a slow progression course of 3 to 5 years followed by stabilization. Since its initial description by Keyzo Hirayama in 1959, most cases have been reported in Asia, particularly Japan and India, although the disease reportedly has worldwide distribution.

Central venous disease (CVD) is a serious complication in hemodialysis patients. Neurological manifestations are rare. We describe a female with end-stage renal disease with throbbing headache accompanied by paresthesia, weakness, and abnormal posture of her right hand during dialysis sessions. Motor symptoms completely resolved after each dialysis session, although the headaches persisted for several hours. No neurological deficit was evidenced on physical examination. Digital subtraction angiography identified an incomplete thrombosis of the left brachiocephalic vein with retrograde flow in the internal jugular vein, sigmoid sinus, and transverse sinus on the left side. This case illustrates that cerebral venous congestion due to CVD can produce neurological symptoms. Furthermore, we systematically review the literature to identify the characteristics of the cases described so far. This allows clinicians to know the entity and have a high index of suspicion in a hemodialysis patient who develops neurological symptoms.

Objective Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a rare and potentially treatable encephalopathy that usually affects people older than 50 years old and has an acute or subacute clinical presentation characterized by rapidly evolving cognitive decline, focal deficits and seizures. In a small subset of patients the disease can adopt a pseudotumoral form in the neuroimages that represents a very difficult diagnostic challenge. Methods Here in we report a patient with a tumour-like presentation of histopathologically confirmed CAA-RI. Results We also conducted a search and reviewed the clinical and radiological features of 41 cases of pseudotumoral CAA-RI previously reported in the literature in order to identify those characteristics that should raise diagnostic suspicions of the disease, there by avoiding unnecessary surgical treatments.Conclusion The therapy of CAA-RI with steroids is usually effective and clinical and radiological remission can be achieved in the first month in approximately 70% of cases.
